Color-Changing Pixels for Transparent Displays with Black Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent display technologies face difficulties in displaying black pixel information, as they struggle to achieve a clear display effect when red, green, and blue sub-pixels do not emit light, leading to issues such as unclear hair portions in portrait images.
Innovation Solution
Incorporating color-changing pixels with transparent and black states into pixel groups, allowing the display panel to switch between transparent and black states, ensuring high light transmittance for transparent display and enabling the display of black pixel information by adjusting the state of these pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent display technology is used, then light transmission and transparency are improved, but the ability to display black pixel information deteriorates
Solution Approach 1:
The display panel is divided into pixel groups, where each pixel group contains multiple sub-pixels of different colors (red, green, blue) and at least one color-changing pixel. This segmentation allows different regions within a pixel group to perform different functions: color sub-pixels provide color display while color-changing pixels provide transparency or black state control, thereby resolving the contradiction between maintaining transparency and displaying black pixel information.
Solution Approach 2:
The color-changing pixels can switch between different states (transparent state and black state) by changing their optical parameters. This parameter change capability allows the same pixel structure to achieve both high light transmission (when transparent) and effective black pixel display (when in black state), directly resolving the technical contradiction.
2Loss of information
If color pixels are used for display, then color information is improved, but the transparency of the display panel deteriorates
Solution Approach 1:
Each pixel group is segmented into color sub-pixels (red, green, blue) and color-changing pixels. The color sub-pixels are responsible for color display while the color-changing pixels maintain transparency or provide black state. This functional segmentation allows the display to achieve both color information display and light transmission without mutual interference.
Solution Approach 2:
The pixel group structure integrates multiple functions: color display (through colored sub-pixels), transparency (through color-changing pixels in transparent state), and black pixel display (through color-changing pixels in black state). This multi-functionality allows a single pixel group to handle both color information and transparency requirements simultaneously.

AI summary
A display panel and a display apparatus are provided. The display panel includes a display area. The display area includes color pixels and pixel groups. The color pixels include a first pixel, a second pixel and a third pixel that have different colors from one another, each of the pixel groups includes one first pixel, one second pixel, one third pixel and at least one color-changing pixel. An operating state of the at least one color-changing pixel includes a transparent state and a black state. The display panel provided by the present disclosure can achieve a transparent display effect, and can also display black pixel information in an image by using a black state of the color-changing pixel, which solves the technical problem in the related art in which transparent display is difficult to display black pixel information in the image.
